[vtkusers] interactively (visually) change Brightness and Contrast

[Alessandro]

I got your point. Mine is that I need to move the way user interact to change brightness and controll from the vtkInteractorStyleImage, so I'm looking for something that simply allows the modification on runtime. Is there something like that?
